So, this thing is basically a 2/2 for 5 with a regen of 2. Do I really need to go into more detail about why this thing is so bad? Alliances had some pretty powerful cards, but this is definitely not one of them. Even if you gave this vigilance somehow, it's still just a 4/2 for 5 with regen which, while better than its original form, is still far from "good" since its regen will still give an opponent life. It's not so much a "steam beast" as a "steam hindrance".
Pros: Colourless 4/2, regen
Cons: Gives an opponent life on tap
